Samsung Announces New ATSC Receiver Chip

Samsung has introduced a new ATSC DTV receiver chip that it says, “boasts a 30 percent higher reception success rate” than its previous design. The receiver chip can also demodulate digital cable QAM signals.

“The S5H1411 offers a higher reception success rate than other devices in multipath environments where signal interference is high, such as densely populated urban areas; dynamic environments with serious signal distortion among many moving vehicles; environments with major signal phase errors because of cable retransmission and remote areas where reception is generally poor,” the company said in its announcement.

Samsung claims this is the first ATSC receiver chip to use 65-nm technology. As expected, the smaller chip size reduces power consumption--Samsung says it requires 20 percent less power than current chips, making it ideal for portable products.

Dr. Do Jun Rhee, vice president of the channel development team at Samsung, said “Our development of a digital TV receiver chip that boasts the industry’s best performance demonstrates Samsung’s leadership in ushering in the digital TV era, From the third quarter of this year, we expect to install the new device in digital TVs bound for the American market strengthening our competitiveness and standing there.”
